Frequency Modulation (FM) CHIRP
• Virtual pulse compression at RX
L l l th d t t TX• Longer pulse lengths and greater power at TX
• With very distinct auto correlation via implementation of Barker code in RX signal processingg p g
• Enables
• Significantly longer pulses with higher energy
• Increased bottom resolution especially at swath edge
• Increases Signal to Noise Ratio, which increases
• Acoustic performance in terms of Range and swath width
• Improves sediment penetration of sediment profiler
